- Input Reverse Polarity: Protection for unlimited time
- Under-Voltage Lock- Out: Unit shuts down below 15V ± 1V. Resumes operation at 17V ± 1V. Min. hysteresis 2V.
- Over-Voltage Lock-Out: Unit shuts down above 54V ± 2V. Output
- Active Over-Voltage Protection: Secondary control circuit takes over if output voltage exceeds 110% ± 5% of nominal voltage.
- Passive Over-Voltage Protection: Zener diode installed on output terminals, selected at 120% ± 10% of nominal voltage.
- Peak Load Duration Limiter Peak load is enabled for up to 4 seconds. Beyond this, output voltage folds to limit the output power to the nominal value.
- Short Circuit Protection Output voltage turns off and on periodically with low duty-cycle (hiccup) to protect system conductors and converter from short circuit. General
- Over Temperature Protection: Output shuts down if base plate temperature exceeds +105C ± 5C. Automatic recovery when baseplate temperature returns to below +95C ± 5C.
- POR: Protection Override signal (BATTLE SHORT function) overrides over temperature protection and input over/under-voltage lock-out. Environmental Conditions Meets MIL-STD-810F Temperature Operating: –55 C to +85 C (at baseplate) Storage: –55 C to +125 C Altitude Method 500.4 Procedures I & II Up to 70,000 ft. Operational Salt Fog Method 509.4 Humidity Method 507.4 Procedure I Up to 95% RH Vibration (random) Method 514.5 Category 24 – General minimum integrity exposure IAW Figure 514.5C-17 1 hour per axis. Shock Method 516.5 Procedure I – Functional shock Saw-tooth, 30 g peak, 11 ms Reliability 150,000 hours, calculated per MIL-HDBK-217F Notice 2 at +85 C baseplate, Ground Fix conditions. Environmental Stress Screening (ESS) Including random vibration and thermal cycles is also available.

To turn the power supply OFF, apply a TTL “0” signal or SHORT to SIGNAL RTN. To turn the power supply ON, apply a TTL “1” signal or leave this pin OPEN. If not used (always ON), leave this pin OPEN. This signal is referenced to SIGNAL RTN. SYNC IN The SYNC IN signal is used to allow the power supply frequency to sync with the system frequency. The system frequency should be 250 kHz ± 10 kHz. When not connected the power supply will work at 250 kHz ± 10 kHz. This signal is referenced to SIGNAL RTN. POR (Protection Override) The POR signal disables the input under voltage lockout, input over voltage lockout, over temperature protection and peak load duration limiter. TTL “0” or short to SIGNAL RTN – Protections are disabled (BATTLE SHORT mode). TTL “1” or open circuit – Protections are enabled (Protected mode). For normal protected operation, leave this pin OPEN. This signal is referenced to SIGNAL RTN. SIGNAL RTN The SIGNAL RTN is referenced to IN RETURN. This is used as grounding for SYNC IN, INHIBIT and POR signals. SENSE The SENSE is used to achieve accurate load regulations at load terminals (this is done by connecting the pins directly to the load’s terminals). The use of remote sense ha s a limit of voltage dropout between converter’s output and load terminals up to 0.5V. When not used connect SENSE to OUT and SENSE RTN to OUT RTN.
